Perhaps from what other top level professional sports leagues pay their players.
I completely don't get why some people are so hostile to another man bettering his life. If it makes zero difference to you whether or not a fighter gets $10,000 or $100,000 for a fight, why go all -well fuck em, they signed a damn contract! But bruh, zero percent is coming out of your pocket, so why hate on the man's shine??
The fact is that this change is coming, with or without the consent of the UFC. You can't ungenie the genie. And the ESPN contract is not into perpetuity. Things will change, because they have to.
The UFC still deserves credit for what they have done thus far. There are fighters that do make bank. Jon Jones, Khabib Nurmagomedov, Daniel Cormier, Holly Holm, Kamaru Usman, probably have no issue their pay. But for every one of them, there the Johnny Walkers still pulling $41K to show.
The UFC has done a lot, but more can be done. Maybe initiate a Fighter Revenue Generator Dept. To come up with ways fighters can generate revenue outside of fights. For example put a surcharge on ticket sales at the venue. In Minnesota, the Target Center holds 19,340 people. If you sell out the card, a $2 surcharge per ticket yields $38,692. Assuming 10 fighters on a 5 fight main card, which each fighter carrying 3 cornermen, $38,692 would give each of the 30 cornermen a $1,289 check. Just from a $2 surcharge, which most ticket buyers would not even notice.
Why would the UFC do this and not just screw over the fighters any chance they get? Because it's the right thing to do, and it reinforces the value to the fighters that the UFC cares about them and their corners and training partners.
That's a great thing for the UFC, that's a great thing for fighters, and it's a great thing for the fans.
